.l ipwation filed December 18- 1905 Serial No. 292,250.

To all whom/"it may 8071,6671. I

Be it known that L'ERIOK D. Bronx, a

"citizen of the United States, residing at Henriette, the county of Pine, State of Minnesota, have invented certainnewand =.,useful 'lmprovements in Miter-Boxes; and I do hereby declare the following to be a full,

clear, and eaiact descri tion of the invention,

l same;

such as will enable. ot iers'skilled in the art to which it appertains to make, and use the This invention relates to miter boxes and has for its object to provide' a miter box'a'r i ranged to cut material at different angles,- and so constructed that a piece of material may be cut at an angle to both its faces and *"fOther objects andadvantages will be apfiarent from the following description."

specification an in which like nurnerals of {in the drawin s forming a portion of this "Ii i'eierence indicate similar parts in the several vfews, Figure 1 is a top plan view of the present miter box, the parts being set to cut slanting angle to the faces.

a board vertically and at a slanting angle to its edges. Fig. 2 is a front view, the uprights being.shiftedintoposition to out a board at a tion on line 3-3 of Fig. 1, taken longitudinally of the supporting member. Fi 4' is a detail section on line 44 of Fig. 2, s rowing the meansfor adjusting the sliding plate.

Referring now to the drawings, the pres-' ent invention comprises a base member 5 havmg a longitudinal passage therein. in which there is revolubly engaged a rod 6 extending atits' ends beyond the member 5 and upon the ends, there are keyed parallel uprights 7 which include each, a pair of inner and outer telescoping members, 8 and 9 respectively.

' The members 8 extend above the members 9 registering. These slots are arranged for the.

and in these upwardly extending portions, there are formed longitudinal slots 10 which openat their ends through the mutually adjacent faces oi the members, and are thus As will be seen, the upri hts '7 are shiftable pivotally with respect to t e member 5 and a I; sliding latch its: is carried by thernember and rights at difi'erentpoints of their pive "movement. This latch is held yieldablymr g operative position b a springlfi engaged between the inneryen of the latch and an rip-= 'wardly-extending block-'15 carried by the member 5. As shown, in Fig. '3, the-latch 14 and at its rearward side b as a verticalopen Fig. 3 is a sec-.

This plate 26 isthus held stationary with respect to the base member 5 and-istthe bed 16'.".

At oppositesides of the plate 26, 16 has portions 16 which are elevated the central portion thereof, the-mutually movable therewith pivotally with-respect to verging rearwardly and bein beveled downwardlyand toward each other and the arrangement is such that the base member and the uprights Ymay beshifted with res eat to.) i

eacho'ther and with respecttothe ed to'tj bring the saw into position to rest against one-.

or the other of these beveled faces. I I Q It win be seenthat,b reason of ;;,thg e1: structure, it is possi Is to varythhligle oi the vertical dimension of the-saw't-witlizrejacent edges of these elevated portions con.-

its

spect to the bed by shifting theuprights 7 with respect to the base member; and it is also possible to vary the angle of the longitudinal or horizontal dimension of the saw with respect to the bed by shifting the base member withirespect to the bed; It is thus possible to cut a piece of material at two angles simultaneously portions 16 or" the bed.

The plate 26 is provided, as willbe readily understood, to supportthe portions of material lying between the upwardly extending Slides 30 are carried by upwardly extending back members 31 which are secured to the bed, the inner ends of these back mem bers terminating at' the innermost portions of the portions 1610f the bed. The mutually adjacent end faces of these back portions converge downwardly as shown, to permit of the above described adjustment of the saw, and the slides are movable to extend at times beyond the inner ends of these back members to receive thereagainst and support'short pieces of material to be cut.

Means indicated at 32 is provided for each of the slides to hold it at different points of its movement.

What is claimed is:

' In a miter box, the combination, with a bed, of a base member provided therebeneath and having a longitudinal passage formed therethrough'; a rod revo'lubly engaged in said passageand projecting atropposite ends beyond said base member; a sawrec-e1 vlng member secured to each end of sa d block finger; a depending arcuate rack secured to the bed and concentric with the base member; a bracket secured to one side of the base member; a latch pivoted con-- trally in said bracket for movement of one of its ends into and out of engagement withsaid rack a laterally-projecting ear carried by the base member directly above the opposite end of the latch; and a spring interposed between the ear-and the last-mentioned end of the latch, for holding the first-mentioned end thereof in engagement with the mole In testimony whereof, I a'flix my signature, in presence of two witnesses.
